Thus, the process vent stream contains toxic air pollutants including arsine and other arsenic compounds, and poses a potential source for the atmospheric arsenic. In generally, arsenic could not seldom be found from ambient, but it would be leaked out and fugitive from processes by human error. Arsenic contamination is considered of great importance, because the amount of arsenic was rapid increased year by year. This aim of this work is to investigate arsenic concentration of the Science Park. This study applied ISCST3 to simulate arsenic concentration of Science Park, and to calculate contribution of sources. The present results showed that wind direction is key factor for arsenic concentration distribution. Pk101 and pk201 were observed to have significant effects on contribution of all sources, because these sources were nearer receptor than others. The health risk of inhalation exposure to arsenic for the person in Science Park of year were between 1.5× 10-8 and 1.2×10-6, the health risk of day were 1.6×10-7 and 4.8×10-6, the health risk of hour were1.6×10-7 and 4.8×10-6. The health risk might be accepted for long tern, but which were greater than require(1×10-6) with health risk for short tern.
